. IMPROVEMIENT IN SASH-HOLDERS.

To all whom it 'ma/y concern.-

Be it known that I, SAMUEL L. LOOMIS, of Byron, Genesee county, ,State of New York,.have invented af new, useful, and improved Sash-Tightene and Holder; and I do hereby declare the following description and accompanying drawings are sucient to enable any person skilled in the art or science to which it most nearly appertains .to make and use my said invention or improvemeuts without further invention or experiment.

The nature of my invention and improvements consists in arranging a traversing slide in a groove in the outside edge of the sash or shutter, resting against elastic rollers placed in recesses in the bottom ofthe groove, the bottom of said recesses being inclined, so that when the sash or shutter is raised, the rollers will descend to the deepest part 0f the recess, which is at the lower end; but when the sash begins to descend, the rollers move up the incline by the traversing ofthe slide, are compressed into a narrower space, react upon the slide, and press it against the side ofthe frame in which the sash traverses. l

.In describing my improved device,-I shall refer'to the accompanying drawings, forming part of thisqspeciiication- Figure 1. being a frbntview or elevation of a shutter or blank sash', with my improved holder and tightener attached to one side, a part of the frame (indicated by dotted lines) being broken out, and a portion of the sash shown in section, vat the depth indicated by the red line on iig. 2;

Figure 2 is a view ofthe sash as seen edgewise, the slide being removed from the groove; and

Figure 3 is a view of the slide, as placed in fig. 1.

In iig. l, 'the sash A is represented asin the act of being' raised, and the slide B, in the groove G, rests upon the elastic rollels C C, in the bottom of the inclined recesses D D, the diameter ofthe rollers and the width of the slidebeing so adjusted that in this position the slide willbe gently pressed against the ame in which the sash traverses.

As soon as the sash begins to descend, the slide B is raised,relatively to the sash, by friction against the frame, and the rollers being thus turned, move' up the incline, both the slide and the rollers taking Aa position .like that indicated by red lines. The elastic rollers will consequently be compressed, and reacting against the slide, will press it against the frame with sucient force to support, by friction, the weight of the sash or shutter.l This, however, may be readily overcome by the strength of ones hand, and the sash raised or lowered at pleasure, being supported by this device at such height as may be desirable. The pressure of the elastic rollers will, at the same time, prevent vibration or the rattling ofthe sash or shutter, and form, between it and the frame, a tight joint, excluding cold air, dust, noise, &c.

The lower shoulder of the slide B, striking against the pin E in the groove of the sash, and the upper shoulder against a fixed block in the upper end of the groove, confines the traversing of the slide within the narrow limits necessary for its successful operation.

It is obvious that when the sash is pressed entirely down, the rollers and slide will have a position like that indicated by the red lines, or somewhat higher, but as soon as it begins to rise, the slide, being held by friction against the frame, will descend relatively to the sash, or fallbehind, and the rollers descend to the .lower ends or deepest parts of the recesses. There will then be but a slight resistance from the friction of the slidev to the raising of the sash.

If the sash or shutter be 'very heavy, the groovel may be made wider, and the length of the rollers iucreased, to, give greater pressure, or if this be inconvenient, the number of rollers and recesses may be increased. Y

The slide B should be made of such'wood, harder or softer, as may be best adapted to produce the proper 'amount of iction in contact with the frame inwhich the sash.' or shutter operates.

lWhat I claim as my invention and improvement in the above-described self-adjusting sash-holder and tightener, is-

The traversing slide Bf arranged in a groove in theA lside or edge of the sash, with the mortises D in said groove, with inclined bottoms, and the rubber or elastic rollers, arranged in the mortises, as described.
